Ullam: Private Diary & Journal
PIN-Locked Journal & Mood Log
Free · In‑App Purchases
A calm, private diary with no account. Lock any diary with its own PIN, track your mood, and keep it all on your iPhone and your own iCloud.
Ullam is a calm, private diary for your daily thoughts. No account, no tracking, no servers reading your life — your journal is stored on your iPhone and synced only through your own iCloud.
WRITE WITHOUT WORRY
• Beautiful, distraction-free editor with rich text, photos and your own emojis
• A warm day/night theme that follows the time of day
• Color-code each entry by mood, and tag it with a category
PRIVATE BY DESIGN
• Lock any diary with its own PIN — locked diaries are encrypted with AES-256, using a key derived from your PIN
• Face ID / Touch ID unlocks the app; every hidden diary always asks for its PIN
• Hidden diaries stay out of your main list and never open without their own PIN
• Everything else is protected by your iPhone's built-in data protection and stays on your device or in your personal iCloud. We never see it.
FIND ANY MEMORY
• Calendar view of your month, with mood at a glance
• Filter the calendar by category to instantly find what you wrote
• Track your writing streak and daily word goal
• Home & Lock Screen widgets: streak, mood, daily goal and a fresh writing prompt
OWN YOUR DATA
• Start faster with templates: Gratitude, Daily Review, Travel Log, Dream and Goals
• Export an encrypted backup protected by a password only you know, and restore it on this or a new device
• Share any single entry as Markdown
• Moving from Day One? Import your JSON export, photos and tags included — or a folder of Markdown or text notes
BRING YOUR DAY IN
• Journaling Suggestions on iPhone: pick a moment from your day — photos, places, music, workouts — and Ullam adds it to your entry. Only what you choose is shared with Ullam.
• Optionally save each day's mood to Apple Health as State of Mind. Ullam never reads your Health data, and moods in PIN-locked diaries stay in Ullam.
ON-DEVICE AI (PREMIUM)
• A writing assistant that helps you continue, rephrase or reflect, plus tag suggestions — running entirely on your device
• Requires an iPhone that supports Apple Intelligence, on iOS 26 or later
